INTERNAL-coMBUsTIoN ENGINE.

Specification of Letters Patent.

Patented July 30, 1918.

Application filed .Tune 25, 1917. Serial No. 176,830.

To all whom t may concern:

Be it known that I, ANTON RAIA, a citizen of the United States, residing at Garfield, in

the county of Bergen and State of New Jer-- to an improved valve mechanism and the cooperative ports.

One of the objects cf this invention is to provide, in connection with a multiple cylinder'engine, a multiple valve member of improved and very eEective construction.

Another object of the invention is to pro`A vide a valve member which not only allows the entrance of the combustion fluid into the cylinders, but also operates to force the combustion fluid into the cylinders.

Another object of the invention is to provide a multiple cylinder engine with counterpart valve members one of which forces the combustion fluid into the cylinders, while the other creates a suction for sucking the products of combustion from the cylinders Another object of the invention is to provide means whereby the valve members are allowed to be easily removed and replaced when necessary for cleaning or repairing.

Other objects and advantages may become apparent to persons who read the followingl detailed description and claims in connection with the accompanying drawings, in which:

Figure 1 is a horizontal sectional view through one form of embodiment of my improved cylinder casting and through one of the valve members carried thereby:

Fig. 2 is a vertical sectional view taken along the line 2-2 of Fig. 1:

Fig. 3 is a somewhat modified form of ernbodiment of the invention;

4t is an enlarged vertical sectional view taken on the line 4-4 of Fig. l: and

Fig. 5 is an enlarged fragmental vertical sectional view taken on the line 5--5 of Fig. 1.

Referring to these drawings in detail, in which similar reference characters correspond to similar parts throughout the several views, the main casting or engine body 10 is of ordinary construction with the exception of the upper portion which comprises the novel construction embodying the flared ports and the seats for the improved valve shafts or members 11 and 12. These valve members are of similar construction, and either of them may be considered as the intake valve member or the exhaust valve member; but, for the sake of convenience in describing the device, the member 11 is considered as the intake member, and the member 12 is considered as the exhaust member.

The shafts or valve members 11 and 12 are each hollow throughout the greater portion of its length, but each is closed or plugged at one end by means of a core or filler 13, and at its other end, by means of a stub shaft 14.- on which is carried a gear wheel 15; the stub shaft being secured within the tubular valve member by any appropriate' means,

Bearings or valve seats 16 and 17 are provided for the respective valve members 11 and 12, into which are fitted the annular ribs 19 which are formed around the valve members 12 and 13. The ribs 19 are arranged in pairs, and between the ribs of each pair a valve-port 20 is provided for the intake member, while valve-ports 21 are provided for the exhaust valve member, these valve-ports being arranged in a stepped or helical series around thc respective valve members, so that each port 20 and 21 comes into effect at a time when the other ports of its helical series is non-effective, as will hereinafter appear more clearly.

In the preferred form of the invention- Fig. 2-the engine embodies a main casting 10 and a cap 10 and between these parts are disposed ports 24 and 25 which are formed partly in each. Valve seats 16 and 17 are formed in the outer vertical walls of the en-y gine body and extend partly into the main casting or block 10 and cap 10.

The valves 11 and 12 are retained in the respective seats 16 and 17 by caps 22 which are secured at their ends to the parts 10 and 10 by means of bolts 23. It will thus be ob- 'tion is made easy by the omission of any Figs'. land 2'is provided'with flared Orin-s wardly diverging intake ports 24: and exhaust ports 25 with which the valve-ports are brought in to registry when the valve members are rotated.l Because of the in wardly flared intake ports, the combustion fluid is allowed'to expand as it enters thefrespectivecylinders'26'; and because of the iny wardly flared or outwardly converging exhaust ports, the products of combustion are compressed as they are forced outward into the exhaust valve member. In other wor-ds the compression of the products fof ycombusobstruction, between the cylinder andY the exhaust valve member, other than the plain and smooth walls of the exhaust ports AlthoughV it is considered within the scope of this invention" to rotate thevalve niemv bers 11 and 12 in opposite directions, I'have illustrated means comprising a pair of gear wheels 27 and a shaft 28, whereby the gears 15 and their respective valve members are rotated in the same direction, as is also shown bythe arcuate arrows in Figs. 4; and

5. Referring to the latter figure, and yto e Fig. .1, it will be seen that the valve-member 11 isV provided with an annularseries of blades 29, while the exhaust valve member is provided with an annular series of blades 30. Each blade 29 and 30 is inclined with relationv to the radial line o which passes therethrough However, the direction of inclination of the blades 29 is opposite to'that of the blades 30. This oppositerelation of the blades 29 and 30' is for the purpose of inducing the inward ilow of the combustion fluid and inducing theoutward o-w of the products` of combustion. vTo explain this feature more fullyit should `be understood that 31 represents the universal intake port, and that 32 represents the universal exhaust port. When the valveniembers 11 and 12 are rotated in` thegvdirection of their arcuate arrows, the blades 29'V are rotated in such' direction fas to ldrawthe Huid `from Athe unie versal'intake port into the universalintake time, the universal exhaust valve member 12 is carrying its blades 30 in such direction as to gather the products of combustion from its interior and to discharge such products of combustion into the universal exhaust port 32. It will be seen, therefore,

that the blades 29 coperate with the pistons 33 Vfor effecting the intake of the combustion fluid, while the blades 30 coperate with the pistons 33 for 'effecting the exhaust of the products of combustion.

7 `In the modified form shown in Fig. 3, the main casting 10a differs from the casting 10,

vin that the cap 10b is separable and is se# cured in positioiion the casting 10Fby means ofscrews or bolts 23a. Therefore, the ports 24a and 25.a are each approximately half formed in the lower ycasting 10, and half formed in the upper casting or ycap 10b. The cap' 101 may -be'forme'd in one piece and comprise cylinder heads for theV re-V spective cylinders 26, vor eachA cylinder vhead may be separable from the other .cyliifidenY heads. l Y

From the foregoing, it will be, seenV that I havejprovided a novel. construction and are` i rangement of valves land portsl which will greatly improve the efficiency. yof internal Y combustion engines, and it is believed that this novel construction and arrangement will become very popular and meet v-with* great commercialsuccess. Y

Although I have described these embodiments of the invention in minute detail, it is to be understood that I do not limit my invention to these exact details of construction, but my invention embraces such modiiications that fall lwithin the scope of the appended claims.
